Had a great, 4 hour Bull Master Magnum session last week. I took some pictures at roughly hourly intervals. It's interesting how the swelling progresses. The BM is basically a long 4" wide cylinder, with a pocket for penis and side pockets for sac expansion. You'll notice a crease on the side of my sac, where the BM sac pocket begins. In first hour or so, my nuts get huge, while the skin of my sac is slowly filling and getting thicker. By the end of the 4 hour session, my nuts are huge, and my sac skin is about 1" thick, if I pinch it. Hope you enjoy these pics as much as I enjoyed making them. Happy pumping. Kel

808 - Thanks for the compliment! I got a new Flip video camera and I made the snap shots from a series of short video clips. It was interesting to do the time series, as it seems to take a long time to begin filling the cylinder. You can see the growth progression each hour. Take care and happy pumping. Kel

Cameo - You bet! I really like my Bull Master. It's a comfortable tube, and is designed to stretch and somewhat shape your package. If you get one, get an STJ silicone seal to go with it. It's super comfortable and stretchy and is worth the extra $$. I'd like to add a Monster Tube to my collection as well. I think the combination of these two tubes would make for a totally great pumping regime. Best of luck if you decide to go with the Bull Master. Kel

i agree with K, the "silicone" seal ring from pumptoys.com is superior to the other ring they sell. softer and stretchier...good when balls are huge. i had the other ring but after a while (2yrs?) it begins to deteriorate and shrink and get oily (had 2 do that).

H - Thanks! My dream is to pack my BullMaster, but no, I don't yet. What you see in my pics is about the max I've gotten so far. My balls and cock swell into the pockets, but haven't completely filled them up yet. My routine is to stay fairly well shaved, lube my balls and cock with olive oil before each session, wet pump with about 20 oz or so of warm water, use a heating pad under my BM, and pump at about 5" Hg or so, occasionally cycling down to 0", and pump for 2 - 4 hours a session. After about 1 1/2 - 2 hours, I hit a "sweet spot" where pumping feels great, even at higher vac levels. In the first hour or so, my nuts expand. In hours 2 - 3, my sac expands to the max, with the skin being about 1/2" thick, or 1" thick when pinched. All in all, I find the BM to be a very comfortable tube, that tends to stretch your sac over time, hopefully leading to big low hangers.

I see you have a BM too. What are your experiences and thoughts about this tube? Happy pumping! Kel

Thanks Kel! I think we are at a similar stage. My balls swell into the side pockets after about 2.5 hours at just below 5 Hg. Feels great. I do dry pumping mostly and I seem to achieve the best results by catching up with magazines while tucked up in bed on a lazy Sunday morning
